why can't the OCR in Xsane read my document accurately?


I have virtually no experience with OCR in XSane or other Linux scanning software, because until recently, every document I've ever scanned in a Linux program contained no text. I have an old (twelve years old) typed letter, and decided to scan it and use OCR.

The results were very disappointing. It's 90% gibberish! Obviously I can't settle for it. Do you get results like this when you try to OCR a document in Xsane?

Or is it probably not the software but the scanner? My scanner's used, I acknowledge.

I hadn't thought of the obvious--increase the resolution. It had been only 75. That helps very much, but the results are still disappointing. I pushed it all the way up to 1200 (maximum on this scanner), but I;m still reading plenty of errors.

Since I don't use OCR much, I have no idea if it's reasonable to expect 100 percent accuracy or if the technology is a work in progress.

Let's let XSane tell the story,

Quote:
What is XSane?

X Sane is a graphical scanning frontend. It uses the SANE-library to talk to scanners. This means that XSane does not support any scanners itself. If you have any problems or questions that are related to your scanner then please contact the author of the sane-backend that supports your scanner or for general questions contact the SANE mailinglist. Here you can find out which scanners are supported by the SANE-library.

XSane is designed for acquiring images with scanners (there are other devices like cameras and videodevices supported by SANE, but XSane is not designed for that purpose). You can scan to file, do a photocopy, create a fax, create and send a mail and start XSane from the GIMP as gimp plug in.

If you do not know SANE please take a look here at first. For further information please read the Documentation of XSane.

It also may be interesting for you to read the report about SANE and XSane of the german computer magazin ct (year 1999 number 21 page 190).....
http://xsane.org/xsane-introduction.html

It doesn't look like Xsane has been upgraded in many years: http://xsane.org/index.html

The SANE Library,
